Animal experimental models have been developed to understand the mechanisms involved in pain response, as well as to discover novel pharmacological and non-pharmacological anti-pain therapies. Due to the genetic tractability, similar physiology, low cost, and rich behavioral repertoire, the zebrafish (Danio rerio) has been considered a powerful aquatic model for modeling pain responses. Here, we summarize the molecular machinery of zebrafish to recognize painful stimuli, as well as emphasize how zebrafish-based pain models have been successfully used to understand specific molecular, physiological, and behavioral changes following different algogens and/or noxious stimuli (e.g., acetic acid, formalin, histamine, Complete Freund's Adjuvant, cinnamaldehyde, allyl isothiocyanate, and fin clipping). We also discuss recent advances in zebrafish-based studies and outline the potential advantages and limitations of the existing models to examine the mechanisms underlying pain responses from an evolutionary and translational perspective. Finally, we outline how zebrafish models can represent emergent tools to explore pain behaviors and pain-related mood disorders, as well as to facilitate analgesic therapy screening in translational pain research.Gastrointestinal (GI) cancer is one of the most common cancers globally. Genetic and epigenetic mechanisms are involved in its pathogenesis. The conventional methods for diagnosis and screening for GI cancers are often invasive and have other limitations. In the era of personalized medicine, a novel non-invasive approach called liquid biopsy has been introduced for the detection and management of GI cancers, which focuses on the analysis of circulating tumor cells (CTCs) and circulating cell-free tumor DNA (ctDNA). Several studies have shown that this new approach allows for an improved understanding of GI tumor biology and will lead to an improvement in clinical management. The aim of the current review is to explore the clinical applications of CTCs and ctDNA in patients with GI cancer.Coronavirus disease 2019 (COVID-19) has spread worldwide and poses greatly threat to global health. COVID-19 also has an unneglected effect on migraine patients. Migraine attack frequency as one of migraine characteristics, its impact during COVID-19 deserves further research. We aimed to evaluate whether migraine attack frequency during COVID-19 pandemic differed from pre-COVID-19, and explore their possible influencing factors during the pandemic.
This prospective cohort study enrolled 187 migraine patients who came from the Department of Neurology of West China Hospital from October 2019 to December 2019. After inclusion and exclusion criteria, a total of 157 patients were included. We collected demographic data, clinical characteristics and epidemiological contact information and followed up on March 2020. Then Paired-Samples T test, logistic regression and interaction tests were used to analyze data.
We found that value of migraine attack frequency was 2.47 ± 1.12 before and 3.54 ± 1.79 during COVID-19 (P&lt;0.0001). Then we divided patients into two group based on the difference of migraine attack frequency between COVID-19 period and pre-COVID-19 and employed logistic regression analysis. In the logistic regression analysis, divorced status (OR=6.53, P=0.0453), good sleep pre-COVID-19 and poor sleep during COVID-19 (OR=3.11, P=0.0432) had independent effect on migraine attack frequency during COVID-19 pandemic. And we found no interaction in the poor sleep during COVID-19 between various subgroups.
Migraineurs may suffer from more frequent migraine attack during COVID-19 pandemic. Pay more attention to marital status and assessment of sleep status may contribute to adjusting suitable treatment strategies of migraine patients during pandemic.

Recent reports suggest that nearly half of the diabetic population remains undiagnosed making diabetic cardiomyopathy (DCM) a clinically relevant entity. In myocardium, chronic hyperglycemia elicits structural and functional abnormalities characterized by ventricular dilation, diastolic dysfunction, fibrosis, and hypertrophy leading to heart failure. Since diabetes is a multifactorial heterogeneous metabolic disorder which cannot be diagnosed or controlled along with coronary artery disease or hypertension, there is an urgent need to understand the underlying molecular mechanisms that leads to DCM and identify potential therapeutic targets. Small non-coding RNAs in particular microRNAs (miRNAs) have emerged as key regulators for several life threatening diseases including DCM. Recent studies have reported that miRNAs not only regulates the fundamental mechanisms of DCM such as insulin resistance, MAPK pathway, PI3K-AkT pathway, oxidative stress, inflammatory signaling but also possesses potential to be a therapeutic or diagnostic target. This review examines the role of critical miRNAs in the onset and pathogenesis of DCM which also depicts high potential as therapeutic and diagnostic in preclinical studies. Further, it highlights the completed and on-going clinical trials going around the globe for diabetes and miRNAs to provide a prospective about the upcoming miRNA therapeutics.Sulfur Mustard is a strong vesicant and chemical warfare agent that imposes toxicity to the lungs, eyes, and skin after accidental or intended exposure.
The current study was intended to explore in vitro and in vivo decontamination properties of electrolytically generated HOCl (hypochlorous acid) against CEES (2-chloroethyle ethyle sulphide), a known sulfur mustard simulant &amp; vesicating agent.
In vitro studies were carried out using UV spectroscopy and GC-MS methods. In vivo studies were perfomred in Strain A and immune compromised mice by subcutaneous as well as prophylactic topical administrion of HOCl pretreated CEES. The blister formation and mortality were considered as end-point. Histopathological study was conducted on skin samples by H &amp; E method. DNA damage studies measuring γ-H2AX and ATM has been carried out in human blood using flow cytometry. Anti-bacterial action was tested by employing broth micro dilution methods. Comparative study was also carried out with known oxidizing agents.
